Abstract
A packaging wrap of a paper and shock absorbing material combination in which the lower layers are cut at specified distances from the edges of the wrap to form strips, while the uncut layer provides hinges about which the strips rotate until lying flat upon the uncut layer, where such strips are secured in position. Because the width of each strip is less than one-half the width of the wrap, a hollow gap is formed in which all or a portion of an article may be inserted. The flexibility of the wrap is increased by crimping the wrap along lines substantially perpendicular to the length of the wrap at intervals along the length of the wrap.
Claims12
A method of constructing a packaging wrap for supporting and protecting at least one article, which method comprises:
- bonding a first layer of flexible material to a first major surface of a layer of shock absorbing material, the layer of shock absorbing material having first and second parallel edges along two sides of the first major surface;
- severing the layer of shock absorbing material along a cutting line, the cutting line being parallel to the first and second parallel edges of the layer of shock absorbing material, and the distance between the cutting line and the first parallel edge of the layer of shock absorbing material being less than the distance between the cutting line and the second parallel edge of the layer of shock absorbing material;
- folding the first layer of flexible material along a fold line located directly over the cutting line so as to fold a portion of the first layer of flexible material back on itself and to rotate the portion of the shock absorbing material between the cutting line and its first edge over onto the first layer of flexible material, whereby a curb is formed by the first edge of the shock absorbing material over the portion of the shock absorbing material between the cutting line and the second edge;
- and
- crimping the shock absorbing material along crimp lines transverse to the first and second cutting lines to facilitate the bending of the packaging wrap along the crimp lines.
